Comparison of ionospheric scintillation models with experimental data for satellite navigation applications

A comparison between two of the most used scintillation models and experimental data is presented. The experimental

Description
Summary:A comparison between two of the most used scintillation models and experimental data is presented. The experimental
 data have been derived from a GPS scintillation monitor developed at Cornell University and placed in Tucuman
 (Argentina), under the peak of the anomaly. The models used (GISM and WBMOD) have been run for the
 geophysical conditions corresponding to the measurements. The comparison is done by subdividing the information
 on the basis of an ionospheric grid of 5°×5° surface square boxes. The comparison has been performed for
 several local times, from 18 LT until 04 LT. Here, only a few cases of particular interest are shown. The goal is to
 understand if the models are able to forecast actual scintillation morphology (from the satellite navigation systems
 point of view) and if they could be used to yield an estimate of scintillation effects on satellite navigation systems.
